confirmed with CVS
again, exit() in sess_write() cause this issue
other modules after session module is not shutdown properly

i don't see any fix in the php4-src/ext/session/ source

i guess i've found the bug
it's a "exception safe" problem as c++
well, not php5 exception, i meant zend_bailout(longjmp)

when write handler issue a Fatal error, will trigger zend_bailout() and
skip ALL other modules rshutdown, including the one right after
session_flush_data();

session.c:
static void php_session_flush(TSRMLS_D)
{
    if(PS(session_status)==php_session_active) {
        php_session_save_current_state(TSRMLS_C); <-- NOT exception
safe using for mod_user.c
    }
    PS(session_status)=php_session_none; <- WON'T executed when
zend_bailout
}

suggested fix:
mod_user.c :: function PS_WRITE_FUNC(user)
chnage
======
    retval = ps_call_handler(PSF(write), 2, args TSRMLS_CC);
======
to
======
zend_try {
    retval = ps_call_handler(PSF(write), 2, args TSRMLS_CC);
} zend_end_try();
======

Code being executed twice really sounds like a problem in the scripting
engine to me. It could be caused or triggered by defects in the tool
chain (buggy compiler optimizer, broken bison/flex).

Please retest with current Stable snapshot from snaps.php.net.
